#' @title Number of chronic conditions (5 chronic conditions)
#' 
#' @description This function generates a derived variable (number_conditions)
#'  that counts the number of chronic conditions a respondent has. This function
#'  takes 5 CCHS-defined conditions (heart disease, cancer, stroke, bowel
#'  disorder, and arthritis), and well one derived variable (respiratory
#'  condition) to count the number of conditions a respondent has.
#'  
#' @param CCC_121 variable indicating if respondent has heart disease (1 = 
#'  respondent has heart disease, 2 = respondent does not have heart disease)
#' 
#' @param CCC_131 variable indicating if respondent has active cancer (1 =
#'  respondent has active cancer, 2 =  respondent does not have active cancer)
#' 
#' @param CCC_151 variable indicating if respondent suffers from the effects
#'  of a stroke (1 = respondent suffers from stroke effects, 2 = respondent
#'  does not suffer from stroke effects)
#' 
#' @param CCC_171 variable indicating if respondent has a bowel disorder (1 =
#'  respondent has bowel disorder, 2 = respondent does not have a bowel
#'  disorder)
#' 
#' @param resp_condition_der derived variable indicating if respondent has a
#'  respiratory condition (1 = respondent is over the age of 35 and has
#'  a respiratory condition, 2 = respondent is under the age of 35 and has a
#'  respiratory conditions, 3 = respondent does not have a respiratory
#'  condition). See \code{\link{resp_condition_fun1}} for
#'  documentation on how variable was derived.
#'
#' @param CCC_051 variable indicating if respondent has arthritis or
#'  rheumatism (1 = respondent has arthritis or rheumatism, 2 = respondent does
#'  not have arthritis or rheumatism)
#'
#' @details mood disorder (CCC_280) was not asked to respondents in the 2001
#'  CCHS survey cycle. This mean respondents in this cycle will only be able to
#'  have a maximum of 6 chronic conditions as opposed to 7 for respondents in
